diazomethane is a toxic yellow gas that is both sensitive and explosive. however, it is a useful reagent in the laboratory to make key intermediates by reacting with carboxylic acids in a quick and clean reaction. draw the expected organic product of diazomethane with the carboxylic acid. draw hydrogens on the oxygen and nitrogen atoms, where applicable. the starting material is a benzene ring where carbon 1 has a carboxylic acid substituent. carbons 3 and 4 are fused with a 5 membered ring. carbon 3 is bonded to an oxygen which is bonded to c h 2 which is bonded to an oxygen which is bonded to carbon 4. this reacts with a negatively charged c h 2 n triple bond n where the center n is positively charged.
